Original application filed February 20, 1914, Serial No. 819,982. Divided and this application filed December 29, 1914. Serial No. 879,560.

To all whom it may concern:

Be it known that I, SAMUEL H. CoNwELL, a citizen of the United States, formerly of Chicago, Illinois, now residing at Tarentum, in the countyof Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in- Release-Rigging for Car-Couplers, of which the following is a specification.

In the drawings: Figure l is a top plan view of the end of a car, broken away, with my invention applied. Fig. 2 is a front elevation of the same. Fig. 3 is an enlarged top plan view and Fig. +1 is a side elevation of the end portion of the pin operating crank. Figs. and 6 are-side elevations of the end portion of a pin lifting lever showing other embodiments of my invention. Fig. 7 is an enlarged perspective view of the endof the pin operating crank of the rock shaft. Fig. 8 is an enlarged detail perspective view of the keeper.

The reference numeral 1 designates a car of any approved construction, to which are secured brackets 2 (one only being shown) in which the rock shaft 3 is journaled. The coupler 4 and its pin 5 may be of any approved construction.

One of the objects of my invention is to provide means, in a car coupler release rigging, to permit a flexible joint between the pin lifting element and the operating mechanism, whereby the said pin lifter is free to travel backward and forward with the draw bar in bud and draft, and further to pro vide means to lock the said pin lifter on the operating member against accidental displacement; and'with these and minor objects in view my invention consists of the parts and combination of parts as will be hereinafter pointed out.

The inner end of'the rock shaft 3 terminates in a crank 6 extending, when the lever is in position on a car, forwardly from the car over the coupler and terminates in. a forked or bifurcated end, the arms 7 of which terminate in an offset 8 the lower edge of which is rounded, as at 9, and merges into the lower edge of the arm, while there is an abrupt shoulder 10 between the upper edge of the offset 8 and the upper edge of. the arm as more clearly shown in Fig. 7.

11 is a keeper provided with openings therethrough through which the arms '4' pass as the keeper is being placed in position on said arms.

2 7 is a key hole in the keeper through which the cotter pin 13 passes to secure the keeper on said arms, said key also passing through said arms.

r 14:. is a portion depending from the outer portion of the offset 8 and constituting a shoulder.

15 is the pin lifter the lower end of which is constructed to engage the locking pin 5 of the coupler. The upper end portion of the pm lifter passes through the arms 7 and terminates in a T head 16 which rests on the top of said arms back of the keeper 11.

In Fig. 5 I have shown the arms 17 terminating at their outer ends in a horn or return bend 18. 19 is the keeper, 20 the cotter pin and 21 the pin lifter having the T head 22.

In Fig. 6 I have shown the outer ends of the arms 23 provided with lugs 24 constituting shoulders against which the keeper 25 bears. 26 is the cotter pin, and 27 the pin lifter having the Thead 28.

The purpose of the band or keeper with the cotter 'pin running through it is to prevent the pin lifter from being pulled out from between the arms of the forked end of the crank 6. H In case the cotter pin should become lost or broken the offset on the ends of the arms would prevent the keeper from slipping off. The different positions'of the keeper, shown in dotted lines, show the course it would have to take to be removed from the arms after the removal of the cotter pin. f

This is a division of my application filed February 20, 1914, Serial No. 819,982.

"fbly connected with the locking pin, a keeper spanning said forked end, the members of the forked end terminating in an offset to prevent the keeper from accidentally sliding off of said forked end, and an operating handle.-

2. In a'release rigging for car couplers,

an operating shaft and an operating handle therefor, a lock pin lifting lever at the inner end of said shaft terminating in a forked end, the arms of which terminate in an offset, a keeper keyed to said forked ends back of the offset, and a lock pin lifting link loosely mounted in said forked end back of the keeper; said offset serving to prevent the keeper from accidentally sliding off of the pin lifting lever in the event of its keyed connection with the forked ends becoming broken.

3. In a release rigging for car couplers, a rock shaft, and an operating handle therei for, said rock shaft terminating at its inner end in a fork, each arm of the fork having two offsets on its outer end portion, a keeper mounted on said arms back of said offsets, a key securing said keeper to said arms; said offsets serving to prevent the keeper from accidentally sliding off of the arms in the event of said key being removed.

4. In a release rigging for car couplers, a rock shaft and an operating handle therefor, said rock shaft terminating at its inner end in afork, each arm of the fork having two oppositely disposed shoulders, a keeper mounted on said fork, a ke securing said keeper on said fork; said 0 sets and shoulders serving to prevent the keeper from accidentally sliding off the fork in the event of the key being removed.

In testimony whereof I aflix my signature in presence of two witnesses.

SAMUEL H. CONWELL.
